XCMG Asphalt Concrete Paver RP756 Road Construction Machine 7.5m
RP756 is a kind of new generation multifunctional paver. It is
completely upgraded with new technology, featuring excellent
performance, simple operation, and superior performance/price
ratio. With the max. paving width of 7.5m, it is the optimal
equipment for paving various kinds of materials for the
construction of highways. The conveying system and material
distribution system have extra large capacity and they are
independently driven (from left/right), which can meet different
construction requirements. In addition, it is more to operate and
it can achieve optimal paving effect under the most tough work
Power drive technology: efficient and powerful
It is equipped with D6114 diesel engine which is water cooling and
turbocharged, applicable to operations at plateau areas.
The cooling system adopts extra-large radiator, which ensures good
heat dissipation even at high temperature environment.
Material feeding/distribution technology: reliable and durable
High capability of material distribution, large spiral pitch
360mmΦ420 large diameter distribution blade, 28BH reinforced drive
chain, and the drive ability is 25% larger than similar products.
The material distribution box and chain all adopt high strength
design, high transmitted power, and the max. transmitted capability
of the distribution shaft is 5000Nm. It can achieve all buried
material distribution, which can greatly reduce the segregation.
It adopts 2 reverse blades at the middle of the distribution bin,
which can effectively eliminates the segregation belt in the
Control technology: stable and accurate
The drive system adopts left/right independent drive, microcomputer
control technology and constant speed automatic control technology,
featuring good straight travel capability, which ensures stable
speed and that the paving speed will not be affected by the load.
The material level control adopts supersonic sensing technology, in
addition to electro-hydraulic controlled conveying speed, which
ensures automatic control of the height of mixed materials in front
of the screed.
The material distribution system adopt 2 sets of independent closed
hydraulic circuit, featuring independent control and 2-stage
proportional speed regulation.
The automatic electronic leveling ensures high flatness; multiple
sensing mode are available, high automation level, orifice plate
and constant pressure technology… all these ensures the stability
of leveling cylinder speed.
Screed technology: mature and reliable
The most mature and reliable double vibrator gas heating screed.
Stepless adjustable double vibrator frequency, applicable to
various paving conditions.
The screed lifting cylinder has floatation and lock up function,
applicable to various paving materials and work conditions.
It can be equipped with eccentric vibration device.
The powerful heat dissipation system, supersonic material level
control, automatic leveler, imported microcomputer control, travel
reducer, hydraulic pump and key components, centralized lubrication
system, wear resistant steel plate and bearing, etc.
The bottom plate and protection device all adopt Germany imported
extra wear resistant steel plate which is improved by 3 times in
the wear resistance and greatly improves the life of bottom plate.
The centralized forced heat dissipation has good effect; the
specially designed extra-large combined radiator can work normally
when the ambient temperature is 50℃.
The originally imported centralized automatic lubrication system
greatly reduces the maintenance work and prolongs the life of
bearings at the high temperature part, which improves work
efficiency and saves maintenance time.
The crawler undercarriage made up of maintenance-free supporting
wheel and rubber track plate does not damage the road and it is
The triune travel drive device and side cover is convenient for
The centralized control has user friendly interface, and it is
simple and reliable to operate. All the control elements are
installed on the mobile instrument case. The seat can be extended
outside of the cab, and there are two seats, which is comfortable
and convenient to operate.
The left/right material distribution device can move up and down
quickly at the same time, which adapts to different paving
thickness and the site transfer is quick and convenient.
